DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE

Referring now specifically to the drawings, an apparatus for cleaning low lying areas, such as base boards, is illustrated in FIG. 1, and shown generally at reference numeral 10. The apparatus 10 generally comprises a platform base 11, with a center axis main shaft 12 rotatably connected to the base 11 and having a brush 13 mounted at the end of the shaft 12 for cleaning a base board.

The base 11 is preferably rectangular, but can be any variety of shapes. The base 11 is preferably made of ¼ inch thick steel, however, the base 11 can be made of any suitable material. As shown in FIG. 5, the main shaft 12 is preferably connected to the underside of the base 11 proximate the front side of the base 11 by positioning the shaft 12 within a first pair of ball bearing pillow blocks 14, 15. The shaft 12 is also positioned within a first sheave 16 between the pillow blocks 14, 15. A first drive belt 17 is run around the first sheave 16 connected to the main shaft 12 and a second sheave 26 connected to an intermediate shaft 22. As shown in FIG. 5, the intermediate shaft 22 is preferably positioned proximate the center of the underside of the base 11. Preferably, the intermediate shaft 22 is rotatably connected to the base 11 by positioning the shaft 22 within a second pair of ball bearing pillow blocks 24, 25 positioned on the underside of the base 11. Adjacent to the second sheave 26 on the intermediate shaft 22 is a third sheave 36 that carries a second belt 27. The second belt 27 extends upward through an opening in the base 11 and is run around a fourth sheave 46 that is connected to a right angle gear motor 40 mounted on the upper side of the base 11, as shown in FIGS. 3 and 4. As such, the motor 40 drives the fourth sheave 46, which rotates the intermediate shaft 22, which rotates the main shaft 12. Preferably, the motor runs at 175 rpm. A capacitor 45 is used to get the motor 40 up to its operating rpm.

It should be noted that the main shaft 12, intermediate shaft 22 and motor 30 can be operably connected in a variety of ways that imparts rotational motion from the motor 30 to the main shaft 12. As used in this application, the phrases “operably connected” and “operably connecting” refer to any arrangement in which one part imparts motion on another, and does not require physical contact between the belts 17, 27 and the shafts 12, 22. Nor does it require the use of sheaves 16, 26, 36, 46.

As shown in FIG. 5, the main shaft 12 extends laterally from the base 11. The main shaft 12 preferably has a diameter of ⅝ inch and the intermediate shaft 22 preferably has a diameter of ½ inch, however, the shafts 12, 22 can be of any suitable diameter. The brush 13 is mounted at one end of the shaft 12, as shown in FIG. 6. Preferably, the brush 13 has a pin 58 extending from one side that is sized for positioning within a bore 18 formed at the end of the shaft, as shown in FIG. 8. The pin 58 is held in place within the bore by a set screw 19. Preferably, the bore has a diameter of 5/16 inch and is one inch long, however, the bore 18 can be of any suitable size consistent with the size of the shaft 12.

As shown in FIGS. 1, 4 and 5, the brush 13 preferably comprises a plurality of bristles for contacting and cleaning a base board. Preferably, the brush bristles are made of black crimped nylon fibers having a diameter of 0.028 inches, however the bristles can be of any material or size suitable for cleaning base boards. Standard vinyl base boards are generally four inches high. Accordingly, the brush 13 preferably has a diameter of four inches, and the center axis main shaft 12 is preferably positioned two inches above the floor surface.

Engagement of the motor 40 rotates the main shaft 12 and the brush 13 to facilitate cleaning of a base board when the brush 13 contacts the base board. A drum switch 47, positioned on the base 11, has a forward and reverse switch 48 to enable the motor 40 to rotate the shaft 12 in clockwise and counterclockwise directions.

While the Figures show the main shaft 12 extending perpendicularly from the lateral sides of the base 11, the main shaft 12 can be positioned at any variety of angles. In one alternative embodiment, the main shaft 12 extends from the front side of the base 11, such that the main shaft 12 is approximately parallel to the lateral sides of the base 11, and the base boards are cleaned primarily by the lateral bristles of the brush 13.

The apparatus 10 preferably has means for rolling movement on a surface. As shown in FIGS. 1, 2 and 4, the apparatus 10 preferably includes four wheels 41, 42, 43, 44 connected at the four corners of the base 11 by attachment to wheel mounts 51, 52, 53, 54, respectively. The wheels 41-44 preferably have a diameter of eight inches, however, they can have any suitable diameter.

As shown in FIGS. 1 and 6, a handle bar 55 is preferably mounted on the base 11 proximate the rear side of the base 11 to provide a means for the user to push the apparatus 10. A bail lever 59 can be mounted on the handle bar 55 and is operatively connected to the motor 40 by a linkage 49, shown in FIG. 4, so that the user must maintain the lever 59 engaged in order to keep the motor 40 running.

As shown in FIGS. 1 and 4, a container 30 is positioned at the rear of the base 11 and proximate the handle bar 55. Preferably, the container 30 is a pressurized tank and contains a cleaning fluid suitable for cleaning the vinyl base board. A hose 32 is connected to the container 30, extends along one of the lateral sides and the front side of the base 11, and terminates with a nozzle 33 proximate the brush 13, as shown in FIG. 1. A trigger release 34 is connected to the container and positioned on the handle bar 55. By engaging the trigger release 34, fluid in the container 30 is sprayed out of the nozzle 33. Due to the proximity of the nozzle 33 to the brush 13, the sprayed cleaning fluid is applied by the brush to the base board to clean the base board.

The user positions the apparatus 10 such that the brush 13 is in contact with the base board “B” to be cleaned. The user starts the motor 40 and engages the bail lever 59 to keep the motor 40 running and the brush 13 rotating. The user pulls the trigger release 34 to spray a desired amount of cleaning fluid “F” from the container 30. The brush 13 applies the cleaning fluid “F” to the base board “B” and the spinning of the bristles of the brush 13 cleans the base board, as shown in FIG. 2. The user moves the apparatus 10 along the base board by gripping the handle bar 55 and pushing.

In an alternative embodiment of the invention illustrated in FIG. 10 and shown generally at reference numeral 10′, the motor 40 is used to propel the apparatus 10′ as well as rotate the cleaning brush 13. In this embodiment, the fourth sheave 46 is operatively connected by a belt 57 to the rear wheel axle 56 so that rotation of the rear wheel axle 56 imparts rotation of the intermediate shaft 22 and the main shaft 12. As such, the motor 40 rotates the brush 13 and propels the apparatus 10′ along the floor surface by rotating the rear wheel axle 56.
